STREET AND STOP INDICATOR FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Mar. 14:, 1916.

Application filed November 14, 1914. Serial No. 872,253,

To all whom it may concern: 7

Be it known that I, JOVAN I. BozowIoH, a citizen of the United States,residing in the city and county of San Francisco, State of California,(whose post-ofiice address is 24:11 lVoolsey street,) have invented newand useful Improvements in Street and Stop Indicators for Railway-Cars,of which the following is a specification.

This invention relates more particularly to indicators, to be placedwithin street cars and operated from an outside source, to indicate tothe passengers the name of the next street or stop.

Among the objects of this invention are to provide an automaticallyoperated indicator, simple in construction easily installed and reliablein operation; in which the chronological tape may be easily removed andsubstituted, when the car is shifted from one division to another inwhich the intersect-- ing street names will be different.

Other objects and. advantages will appear as the description progressesin connection with the one sheet of drawing forming a part of thisspecification to which'like reference characters have been applied.

In the drawings: Figure 1 is a side elevation of a street car partiallybroken away in cross section, to disclose the installation of thisinvention therein. Fig. 2 is an end elevation of the same in crosssection taken on the line IIII Fig. 1. Fig. 3 is a detail diagrammaticplan view of the inclosing casing shown in cross section disclosing theinterior mechanisms. Fig. 4 is a similar view in side elevation of thestop and chronological strip release mechanism. Fig. 5 is a detail planview of the pivoted trigger mechanism. Fig. 6 is a detail in sideelevation of the manual control of the re-' lease mechanism. Fig. 7 isa' front elevation in detail of the take up reel. Fig. 8 is a plan viewfrom above of the same in cross section taken on the line VIIIVIII Fig.7.

In detail the construction illustrated in the drawing, includes thecar-body 1, mounted upon suitable trucks 2 running upon the rails 3. Theindicator comprises an inclosing casing 4:, mounted in the end of thecar, within convenient sight of the passengers. The front of the casingis glazed as at 5 to expose the chronological strip therethrough. Thisstrip is wound upon the reel 6, and passes over the idlers 7 and 8 andengages the spring take up reel 9. The reels 6 and 9 are mounted uponthe shafts 10 and 11 journaled in the casing 4:. The chronological strip12 is provided with the notches 13 in the edge thereof. The strip 12 iscontrolled by the pawl lei, having the heads 15-15- engaging the notches13 therein. The strip 12 runs behind the guide 16, fixed to the pawl andoverlying the push-rod. The pawl 14 is mounted'on the end of the pushrod 17, that is guided in the casing 4 at the.

top, and passes through the floorlS at the bottom. The rod 17 has thecollar 19 fixed thereon to engage the adjustable stop 20, to regulatethe drop of the pawl 14. A thrust collar 21 is fixed on the shaft 17beneath the floor,and is engaged by the yoke 22 on the end of the lever23, pivoted at 24 on the bracket 25, fixed to the underside of the carfloor. This lever is provided with a downwardly extending trigger 26,adapted to engage the trip 27 attached to the rail 3, at the variouspoints along the right of way where it is desired that the indicatorshould be released, to designate the name of the intersecting pointsbeing approached. The trigger is restored to its normal verticalposition by the tension of the spring 28, attached to the underside ofthe car floor and to the extension 29, on the opposite side of the pivot24 from the lever 23.

j The indicator is operated substantially as follows: The tension of thespring 30 con fined within the reel 9 is wound up by the conductor, whoplaces a key upon the squared end 31 of the shaft 10; the tension of thespring being wound up as the strip 7 With the chronological strip instarting position', the car progresses until'the trigger 26 passes overthe first trip 27; thisforces the trigger backward, elevates the yoke22, pushes up the rod 17 releasing the pawl II from the strip 12; theinst-ant that the pawl 14 was released from the strip, the trigger haspassed entirely over the trip 27 and been restored to the normalposition by the tension of the spring 28, permitting the pawl 14. todrop in time to engage the next set of notches 13, that will stop thechronological strip, exposing the designation of the next succeedingintersecting street; this operation being repeated each time the triggerengages a properly placed trip on the right of way. Should a trip bemissing or the trip fail to properly release the strip, a manual controlis provided whereby the conductor at the opposite end of the car mayrelease the pawl as often as necessary, to permit the strip to progressso as to indicate correctly. This manual control consists of the handle32 on the cord 33, passing over the pulley 34; and attached to the bellcrank lever 35 pivoted at 36, adjacent tothe rod 17, the opposite end ofthe lever being pivoted at 37 to the pawl; whereby a pull on the handle32 elevates the pawl 1a.

It is obvious that the mechanism described may be duplicated at oppositeends of the car, if the car is designed to operate in either direction,or the indicator may be so constructed that the reels 6 and 9 may beremoved from the mechanism at one end of the car and transferred to theother, to save the necessity of having two chronological strips, one ofwhich would remain inactive. T he construction of the trigger is suchthat if properly mounted on opposite ends of the car, only one of thetriggers would operate the release mechanism going in one direction.

I have disclosed this invention in its sin1- plest form, but I do notwish to be limited to the particular mechanism shown and describedherein as many variations may be made within the spirit of thisinvention.

I claim:

1. A car indicator comprising areceptacle, a carrying spool 'rotatablymounted in said receptacle, a winding spool rotatably mounted in. saidreceptacle, a ribbon wound upon said carrying spool and connected withsaid winding spool, said ribbon having one edge portion provided withnotches, a rod slidably mounted and provided with an arm. extendingalong said ribbon and provided with teeth for fitting into the notchesthereof to releasably hold said ribbon in a set position, and means forraising said rod to move said teeth out of engagement with said ribbon.

2. A car indicator comprising a receptacle, a ribbon movably mounted insaid receptacle and provided with notches leading from one edge, aslidably mounted rod, a pin carried by said rod and extending along saidribbon upon the opposite side thereof from said rod, a latch armextending from said rod and provided with teeth for fitting into thenotches of said ribbon, and means for moving said rod to a position torelease said ribbon. from said teeth.

8. A car indicator comprising a receptacle, a slidably mounted rodhaving a head at its upper end, a finger extending from the head of saidrod, a latch arm extending from the head of said rod, an indicatingribbon movably mounted in said receptacle and extending between said rodand finger and extending substantially parallel to said latch armwhereby said latch arm may engage said ribbon to releasably hold theribbon in a set position, and means for moving said rod to release saidribbon from said latch arm.

i. A car indicator comprising a receptacle, a ribbon movably mounted insaid receptacle, a slidably mounted rod extending into said receptacle,means carried by said rod for engaging said ribbon to releasably holdthe ribbon. in a set position, a pivotally mounted lever provided with aforked end through which said. rod passes, an abutment collar carried bysaid rod for engagement by the forked end. of said lever, and a triggerarm extending from said lever, movement of said lever in one directionmoving said rod to release said ribbon.

5. An indicator comprising a receptacle, a ribbon movably mounted insaid receptacle and provided with notches leading from one edge, a latchprovided *ith teeth for fitting into the notches of said ribbon toreleasably hold said ribbon in a set position, and means for moving saidlatch to a position to release said ribbon from said teeth.
